Absolutely awesome products

So I haven't actually used these in travel yet due to the pandemic, however I did test the bottles with water inside and packed them into my SeaLine travel liquids pouch to test fit. Here's the thing. I am a lifetime designer and UX Architect. Form, function, and design all matter to me... maybe too much. But I've got to say these gals and guys at Gravel have produced and excellent solution to the issue of packing liquids, because these don't leave wasted space between them and fit nicely in an open liquids pouch. GoTubes were my previous go to, and these appear to be the same quality, with a nicer design and form factor. They fit neatly together in an open pouch. In my particular pouch I could fit 5 of these pretty easily and still have room for toothbrush and paste and other random bits. There is not wasted space between them which is awesome. That's the issue with round tubes like the other's on the market; they leave a lot of wasted space and you can't pack items efficiently. Now the use case where this might not be as great is if you use like a Tom Bihn pouch or something that has individual elastic bands or pockets for each item, I would imagine the round tubes might work a little better getting them in and out, but for me these are a perfect implementation, great design and quality. Nice work Gravel!
